One of the more interactive cases we've seen in a while, Taylor's X Stitch ($32, aka Xstitch / X-Stitch) for the iPhone 4 combines cross-stitched thread with a silicone rubber case. The body of the case is pretty standard, providing full back and side protection as well as button coverage and a fold out Dock Connector cover. Along the back is a 22 x 43 perforated surface used to guide you in creating a cross-stitched pattern; a thin layer of silicone is easy enough to puncture with the included needle, yet provides protection to the unstitched areas. Red, blue, green, and red threads are also included in the package. A free iPhone app from Taylor provides patterns and instructions; you can self-supply other thread if you want to jazz it up.

Editors' Note: iLounge only reviews products in "final" form, but many companies now change their offerings - sometimes several times - after our reviews have been published.
This iLounge article provides more information on this practice, known as revving.
